'unexpectedly-placed' originates from the combination of 'unexpectedly' and 'placed', where 'unexpectedly' is derived from 'unexpected', meaning 'not anticipated', and 'placed' from 'place', meaning 'to put in a particular position'.

'unexpectedly' evolved from the Old English 'un-' meaning 'not' and 'expected', while 'placed' comes from the Old French 'placer'.

Initially, 'unexpectedly' meant 'not foreseen', and 'placed' meant 'put in position'. Together, they convey the idea of being positioned in an unforeseen manner.
